Ectopic Ovary in Morison's Pouch in 16-Year- Old Adolescent with Gastroschisis Presenting with Chronic Abdominal Pain

Background: Ovarian ectopy is usually associated with Müllerian abnormalities. Case: We report a 16- year-old girl, presented with abdominal pain for 2 years. She had a history of gastroschisis surgery, appendectomy and repeated admissions. She presented stabbing pain, cyclic, lasting up to 2 to 3 weeks, she occasionally woke up at night due to pain. MRI showed a right-sided, ectopic ovary in Morison's pouch, between liver and kidney. Expert opinion was that ovariectomy was not indicated and oral hormonal contraception was suggested. Conclusion: This case report prompts a gynecologist to consider diagnosis of ectopic ovary in the adolescents with repeated episodes of abdominal pain, absent ovary on the routine pelvic ultrasound scan, history of gastroschisis or history of abdominal surgery.
